As a games programmer with coming up to 5 years experience, I can attest that this is largely true. At every studio I've worked at, I've been given strange looks for even opening a terminal, and half of them haven't even heard of Vim. Regardless of what the actual strengths and weaknesses of the tools are, most game developers are so heavily wedded to VS and Windows that there is a huge inertia on that side. Personally, the mobile game that I'm developing now is being developed entirely under Linux with GCC and GDB, and although GDB has a bit of a learning curve I now find it easier and quicker than VS.
